Contact Lenses II

At the end of OPT 414 (Contact Lenses II) course, the students should be able to: 1. differentiate and demonstrate the ability to fit different types of rigid gas permeable (hard) contact lenses; 2. describe different types of contact lens modifications; 3. describe systemic diseases that can effect contact lens wear; 4. demonstrate the ability to perform advanced fitting of contact lenses; 5. demonstrate the ability to fit contact lenses for specific needs; 6. describe the knowledge of orthokeratology and its applications; 7. describe the knowledge of refractive surgery and its implications to contact lenses; 8. identify the trends in contact lenses development; 9. identify different types and brands available in the market; 10. explain the steps involved for contact lens pre-fitting examinations; 11. describe the basic concept of contact lens selection; 12. describe the concept of inspecting and verifying contact lens parameters; 13. explain the concept of contact lens insertion and removal; 14. discuss the evaluation of contact lens fit; 15. describe modification of hard rigid gas permeable (RGP) lens; 16. write contact lens parameters / specifications and order the lens; and 17. explain the concept of checking before dispensing contact lenses.

A continuation of OPT 413. Comparison between soft and rigid gas permeable contact lenses. Fitting techniques for rigid gas permeable contact lenses. Detection and management of chronic and acute complications induced by contact lenses. Advanced fitting techniques for toric and bi- toric lenses. Contact lens management options for special conditions such as dry eye, aphakia and keratoconus (and other corneal irregularities). Scleral lenses. Disposable lenses and replacement regimes. Monitoring contact lens wearers and fitting presbyopic patients. Alternative management of refractive errors such as orthokeratology and refractive surgery. Laboratory sessions include pre-fitting examination, contact lens selection and fitting, evaluation of fit, insertion and removal. Lens inspection and verification. Lens modification (Hard or rigid gas permeable lens) ordering and dispensing.
